摘要： The present disclosure provides a transparent alumina-based plate, and a hot-pressing method to make the transparent alumina-based plate from platelet alumina. Alumina powder with a platelet morphology was hot-pressed to transparency with pre-load pressures of about 0-8 MPa, maximum temperatures of about 1750-1825° C., maximum pressures of about 2.5-80 MPa, and isothermal hold times of 1-7 hours. A novel alumina-based plate has been prepared, wherein the plate has a thickness of 2-5 mm, an in-line transmission of at least 60-75% for a light with a wavelength range of 645-2500 nm, an in-line transmission variance of

摘要： A microwave ferrite material for a third-order intermodulation circulator and a preparation method therefor, the chemical formula being Y3-aCaaSnaInbMncFe5-a-b-cO12, 0.1≤a≤0.3, 0.01≤b≤0.1, 0.001≤c≤0.1. The preparation method comprises the following steps: (1) weighing; (2) first ball milling; (3) drying and preheating; (4) second ball milling; (5) granulation; and (6) post-treatment. The microwave ferrite material reduces the intermodulation interference between combined signals, and further improves the performance of communication systems and the coverage and capacity of networks. At the same time, it is ensured that the stability and repeatability of the preparation process are maintained at a good level, being suitable for mass production applications.

摘要： A process for 3D printing articles made of carbon or graphite includes producing a flowable polymeric mixture from a UV permeable and polymerizable polymer or cellulose and a UV crosslinkable resin, admixing the polymeric mixture with sugar and/or cellulose until the mixture has a consistency such that it can be filled into a 3D printer and processed thereby, homogenizing the mixture at room temperature or elevated temperature, filling a 3D printer with the mixture, layerwise printing a shaped article with simultaneous exposure to UV radiation for layerwise crosslinking of the UV crosslinkable resin, cleaning the shaped article, introducing the UV precured shaped article into a furnace and stabilizing the UV precured shaped article in air at a predetermined stabilizing temperature until all volatile constituents have outgassed from the prefabricated shaped article and subsequently high temperature treating the shaped article for carbonization or graphitization in a furnace under protective gas.
